HUBBLE SPACE TELESCOPE
DAILY REPORT #1101
PERIOD COVERED: 0700 EST
Daily Status Report as of 082/1200Z.
1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:
1.1 Completed WF/PC-2 4709 (WF/PC-2 Internal Monitor)
The WF/PC camera was used to make a series of routine visual flat
calibration images to monitor the instrument's performance. The
observations were monitored in the OSS, and the data quality was
assessed. No anomalies were noted.
1.2 Completed WF/PC-2 5109 (A Deep Survey at High Galactic
Latitudes(WC06): Cycle 4)
The WF/PC-1 was used to make long exposure high galactic latitude
observations to learn more about the number and morphology of faint
distant galaxies and the luminosity function of stars in our galaxy.
A total of six observations were received and displayed. They were
reported to be okay, except for numerous recenterings.
1.3 Completed Two Sets of WF/PC-2 5562 (WF/PC-2 Cycle 4 Calibration:
Internal Monitor 3. Darks)
The WF/PC-2 was used to obtain two 30 minute long dark exposures to
provide ongoing calibration of the CCD dark current and to monitor
and characterize the evolution of hot pixels. Both images were
received and displayed in the OSS. They both were reported to look
okay.
1.4 Completed Two Sets of WF/PC-2 5397 (Determination of the
Extragalactic Distance Scale: Cycle 4 High)
The WF/PC-2 was used to make images of galaxy NGC-5457-FL to help
establish the Hubble constant to an accuracy of better than 10% by
measuring the periods of Cepheid variable stars within the galaxy.
Three images were received and displayed. The first image was
reported to look fine. The next two images were okay, but
encountered some recenterings.
1.5 Completed Two sets of WF/PC-2 5570 (WF/PC-2 Cycle 4 Calibration:
Earth Flats, Large Set)
The WF/PC-2 was used to make a set of Earth flat calibration images
using different filters in order to construct high quality flat
fields of the OTA illumination pattern. A total of eight images were
received and displayed. Four images were reported to be saturated,
one was underexposed, two were "streaky", and one was okay.
1.6 Completed GHRS/1 5544 (GHRS Side One Spatial PSF Characterization:
Cycle 4)
The High Resolution Spectrograph (Side One) was used to attempt to
make observations of standard target MU-COL to study the point
spread function characterization. The Large Science Aperture (LSA)
shutter failed to open. The cause of the anomaly is being
investigated. An HSTAR was written.
1.7 Completed WF/PC-2 5476 (Continuum Snapshots of 3CR Radio Galaxies)
The WF/PC-2 was used to make snapshot images of radio galaxy 3C427.0
as part of a continuum survey and to study the galaxy's morphology.
The observations were executed as scheduled, and no anomalies were
noted.
